My mini dozer build

[OTHill]

Interesting. How high of RPM would that be good for? Asking for a rototiller type design. Thanks!

Not really good for steady rotation except very low rpm. My application is where the dozer frame mounts and won't even turn a quarter turn from on ground to full lift.

Thanks on that. I was thinking you all were talking about the bearings on the shafts for the drive sprocket and idlers on the tracks. (dohhh!)

Here's a few pictures of moving dirt. Sorry I don't know how to do videos.

Cool. Fun and learning working together for a productive project.

Here is my latest project. Spent most of a year at it. Has been very satisfying. Engine is 3 cyl. Kubota 20 hp. Drive is fully hydrostatic from a wrecked Massey swather I had given to me. Drive motors are 29 cu.in orbit motors from Princess auto. Brand new mini excavator tracks the single largest expense in the project. Didn't keep track of total time or expense but must be 1500 hrs and 5 or 6 thousand dollars by now. Any parts that could possibly be plasma cut I did on my 4x8 ft. Cnc plasma table including front idlers, rear drive sprockets and track rollers. Total weight might be 1200 lbs. Just guessing though. Top speed is close to 5 mph. Planning a 6 way dozer for it yet to. I'm very new at posting this kind of a thing so please bear with me.View attachment 692193View attachment 692194View attachment 692195View attachment 692197

living my dream, why , why , why ?

I did a similar project few a years ago so I can appreciate all the work OTHill has done.

Beautiful work Nice to have the tools to do something like this.

I would like to find a small tractor to experiment with. Have often thought of taking one, dropping the front axle, and building a subframe to sit it in. Making a sprocket for track drive. It would be more of a high sprocket with two idlers. Using disc brakes with the tractors for secondaries if needed. Making it so it could be swapped out to tires or tracks as needed. I remember the older fords that had the halftrack system that worked well.

Thanks plumbstraight! It is very nice to have tools. It hasn't always been that way. I started out with an old Hobart stick welder and a cutting torch 50 or more years ago and that worked too.
I like your idea of using a tractor the way you mention. You are thinking outside the box. I love that.
